Remember Sodom and Gomorrah? He could have done it Himself. He was training His people in what was right and wrong.

Training his people to go out on murderous rampages? Certainly sounds like a benevolent god. Funny about the cities of the plain, I read somewhere that their crime was not their homosexual urges but because they were not good hosts. (The story comes right after Abraham accepting god in his tent.)
Lot surely is a good host. He offered his engaged daughters to be gangraped. And they wondered why the fiances won't come with them when they fled the city. Must be the trauma that caused them to have a taste for their dad's dick.
There is one part where god orders the Israelites to murder everyone in 60 cities... 60 cities at once! They were ordered to kill all the males and women over 12... the women 12 and under were taken as sex slaves... by the command of god (according to the bible)
It's baffling how the Judeo-Christian/Islamic god and it's followers maintain a prudish manner and yet very obsessed with sex. A large part of the Bible seems to be instructions on how to properly have sex in ways "pleasing" to him.
